MOLD FOR CHIMNEYS AND THE LIKE.

Specification of Letters Patent. Patented June 6, 1916.

Application filed August 14, 1914. l Serial No. 856,831.

To all whom t may concern:

Be it known that I, ViLLiAivr R. DAvis, a citizen of the United States, residing at Dorranceton, in the county ofLuzerne and State of Pennsylvania, have invented certain new and useful Improvements in Molds for Chimneys and the like; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thevsame.

This invention comprehends certain new and useful improvements in molds and has for its primaryy object to provide a sectional collapsible mold which will be especially adapted for forming chimneys and the like.

Another object of the invention is to provide a mold of this character which will be constructed for forming a specific type of chimney and which will be constructed in such manner that the parts ofthe inner and outer forms of the mold may be readily assembled and securely locked together.

The invention has for a further object to provide a device of this character including an outer mold form constructed in sections of simple formation and which will cooperate with the inner mold form to properly support a plastic chimney being molded between said outer and inner form.

The .invention has for a still further object to provide inner and outer mold forms which will be constructed and secured together in such manner that they may be readily taken apart after the chimney is completed and folded in compact form.

With these and other objects'in view as will become more apparent as the description proceeds, the invention consists in certain' novel features of construction, combinationY and arrangement of parts as will be hereinafter more fully described and claimed. c

For a complete understanding of my invention, reference is to be-had to the following description and` accompanying drawings, in which Figure-1 isa vertical section through my inner` Vandouter moldformsin use.; ,Fig.

2 is a transversehorizontal section through the same substantially on the plane of line 2-2 of Fig.` 1. Fig. 3 is a fragmentary top plan view vwith the corner rods `in section.

Fig. v4 is an Venlarged detail section on the plane of line 4-4 of Fig. 1. Fig. 5 is a similar View on the plane of line 5-5 of Fig. 1. Fig. 6 is a detail perspective view of one of the U-shaped clamps. Fig. 7 detail plan view showing the corners of the upper sections of the outer mold forms. Fig.V 8 is a detail transversesection on the .plane of line 8-8 of Fig.`7. Fig. 9 is a isaV standing sections forming the inner mold .form and extending the entire height of the chimney 2 and between the inner form and the other form which will be later fully described. The upper ends of the sections 1 are directed inwardly as at 3 and have suitable openings through which the corner rods 4 are extended, said corner rods 4 being also extended through the inner looped end of the twisted wires 5 which extend through the plastic chimney 2 andthroiigh the inner and outer mold forms.l 4Right angled corner ,strips 6 engage the ends of the sections 1, and are provided with yokes in loops 6, which pass through openings 6b in the sections, and through which pass the rods 4, it being understood that the longitudinal vertical edges of the sections 1 are offset inwardly to bring the right angled portions 6 of the corner strips in alinement with the mainV portions of said sections 1, i

thereby making it possible to construct a chimney with a smooth inner face. The sections of the outer mold form are .held in proper position with respect to the inner mold form by means of the wedge keys 7 engaged through the outer looped ends of the Vtwistedjwires 5.3 It Vwill also be noted that the corner rods 4-have their upper ends loopedto form the handles 8 by means of which said rodsmay be readily forced into position or removed," .said rods 4 also assisting in retainingthe sections of theouter mold form inproper position with respect to the inner v.mold form ,byr'being engaged through the inner ends strips 9 which are engaged over the inwardly directed upper ends 8 of the sections 1 of the inner mold form while the other ends of said connecting strips 9 are engaged over the outwardly directed upper edges 10 of the uppermost sections 11 of the outei` mold form. The opposite ends of the connecting strips 9 are bent slightly' at an angle to the main or inclined portion of said strips and the outer ends are secured to the outwardly directed upper edges 10 of the sections 11 by suitable wedge keys 12 similar to the wedge keys 7 engaged through registering openings in said strips 9 and edges 10. The outwardly directed lower edges 13 of the sections 11 rest upon the outwardly directed upper edges 141 of the sections 15 forming portions of the outer mold form immediately below the uppermost sections 11.

The edges 13 and 11 of the sections 11 and 15 respectively are secured together by the substantially U-shaped clamps 16 which extend through said edges and have the feet 17 formed upon their free ends and extended in opposite directions for engagement against the underface of the edges 14 while suitable wedge keys 18 are engaged through the main or central portions of said clamps 16 and bear against the upper face of the edges 13 of said sections 11, thereby drawing together and clamping said sections 11 and 15. 1t will be understood that the sections 11 and the upper portions of the sections 15 are provided with corresponding offset portions to form the ornamental shoulder 2 of the chimney 2 adjacent the upper portion thereof. In order to securely fasten together the sections 15 of the outer mold form, I have provided two of said sections with outwardly directed ends 19 at right angle to the main portion thereof and adapted to be'securely clamped against the extended ends of the remaining sections 15 by means of U-shaped clamps 16 and wedge keys 18 previously mentioned.

The sections 15 are also connected with the inner form 1 by means of the connecting and bracing strips 2O which extend transversely through the sides of the chimney 2 and have their apertured ends projecting through the inner mold form 1 and the sections 15 of the outer mold form to receive suitable wedge keys 21, similar to the previously mentioned wedge'keys.

Each section 15 of the outer mold form has a downwardly inclined lower edge 22, against the lower face of which is positioned the outwardly directed and slightly inclined upper angle 23 of the substantially W-shaped section 211 of the outer mold section which has the lower edge of its depending angle 25 tially W-shaped section 24 cooperates with the downwardly inclined lower edge 22 of the section 15 to form the downwardly inclined `flange 2 of the chimney 2 and the depending lower angle 25 of the W-shaped section 2st is secured against the portionl of the section 27 of the outer mold form projecting through the roof 26. It will further be understood that certain of the sections 27 have outwardly directed vertical sides 28, which are securely clamped to the extended ends of the remaining sections 27 by the clamps 16 and wedge keys 18 while the lower edges of the sections 27 are bent outwardly in substantially a horizontal plane and engaged against the correspondingly extending upper edges 30 of the lowermost sections 31, the lower edges of the sections 27 being designated by the numeral 29.-

` Thelowerinost sections 81 of the outer mold form are provided with suitable base portions 32 and certain oit said sections 31 have sides 83 extended at right angles and secured against the extended straight ends ofV the remaining sections 31 by the clamps 16 and wedge keys 18. The base portions 32 extend inwardly beyond. the sections 31, and these inwardly extending portions are adapted to be embedded in the brick foundation of the lchimney to support the mold vin proper position upon the brick foundation.

From the foregoing it will be evident that I have provided a sectional mold for chimneys and the like composed of inner and outer mold forms which may be readily assembled and connected and secured in proper position with respect to one another. will also be evident that if desired, the sections 27 of the outer mold form may be left in position after the chimney is completed to prevent leakage around said chimney.

W'liile the preferred embodiment has been shown and illustrated, it will be understood that minor changes in the details of con-y struction and arrangement of parts'may be made within the scope of the appended claims without departing from the spirit ofl the invention or sacrificing any of the advantages thereof.
